Title
Improved temporal psychovisual modulation for backward-compatible stereoscopic display
Abstract
Recently a new information display technique named temporal psychovisual modulation (TPVM) was developed to extend the utilities of optoelectronic displays. A typical usage of TPVM is the backward-compatible stereoscopic display, where a stereoscopic view is perceived with 3-D glasses while a 2-D view of the same scene is concurrently available for naked-eye viewers. The most challenging part of this task is to display a clean 2-D image without ghosting artifacts. In order to reduce the ghosting artifacts, we present an improved TPVM system for backward-compatible stereoscopic display. Different from previous approaches, we rebuild the TPVM system by investigating the light perception process of human eyes, and reformulate the problem as a minimization of the light intensity difference between the target and perceived views. In order to derive the light intensities, we model it as a monotonie increasing function of the pixel intensity consisting of a scaling plus an offset, and incorporate this model into our system. By solving the optimization problem, ghosting artifacts are significantly reduced in the 2-D view. Moreover, a closed-form solution is provided for real-time applications. Experimental results demonstrate that the proposed method is superior to previous approaches in terms of the 2-D view quality, while the quality of the 3-D view remains unchanged.
